Abstract: Aspects of the present disclosure generally relate to wireless communications and, more particularly, to techniques for managing multi-link communications. Some aspects of the present disclosure provide techniques for configuring data unit and control response transmissions on multiple links. The data unit and control responses may be configured such that a control response transmission does not overlap with a data unit reception at a station that is without simultaneous transmission and reception capability.

Abstract: This disclosure provides systems, methods and apparatus, including computer programs encoded on computer storage media, for group formation and sounding for distributed multi-user multiple input multiple output (MU-MIMO). Some implementations include a method of wireless communication. The method includes a sounding preparation phase that includes transmitting, to the plurality of access points, a first frame inviting the plurality of access points to perform a beamformed distributed transmission from the plurality of access points to a group of stations; receiving a second frame from at least one of the plurality of access points based on transmitting the first frame, the second frame including at least one identifier of at least one station in a different basic service set than a basic service set of the first access point; and identifying the group of stations based on the at least one identifier included in the second frame.

Abstract: This disclosure provides systems, methods and apparatuses for implementing full-duplex communications at an access point (AP) without configuring or modifying associated stations (STAs) to operate as full duplex devices. In some implementations, the AP may select at least one of one or more first STAs to transmit uplink (UL) data to the AP, determine a downlink (DL) signal-to-interference-plus-noise ratio (SINR) for each of one or more second STAs, select at least one of the one or more second STAs to pair with the selected at least one first STA for concurrent DL and UL communications with the AP based at least in part on the determined SINRs, and transmit DL data to the selected at least one second STA concurrently with receiving at least a portion of the UL data from the selected at least one first STA.

Abstract: This disclosure provides systems, methods, and apparatus, including computer programs encoded on computer-readable media, for enabling a neighboring access point (AP) to reuse communication resources that are used by an existing spatial reuse group (SRG). In one aspect, an SR element including SR information can be generated. The SR information may indicate that a first group of STAs associated with a second AP may reuse resources of a wireless medium over which packets are transmitted by a second group of STAs associated with the first AP and may indicate a permitted OBSS threshold value for reuse of the resources over the first AP. In some implementations, a wireless apparatus may transmit the SR element that includes the SR information.

Abstract: Certain aspects of the present disclosure provide methods and apparatus relating to distribution networks that utilize point-to-point communication between devices. The method comprises generating a frame with information indicating in which time division duplex (TDD) time slots, in a service period (SP) within a data transfer interval (DTI) of the frame, another apparatus is allowed to communicate. The method further comprises outputting the frame for transmission

Abstract: This disclosure provides systems, methods, and apparatuses for implementing changes to Basic Service Set (BSS) parameters of an access point (AP) in a synchronized manner across multiple physical layer (PHY) formats. In some implementations, an AP may enable STAs that use different PHY formats to implement the changes at substantially the same time. For example, the change in BSS may be aligned with a target beacon transmission time (TBTT) of a first PHY format, and the AP may broadcast information, in a second PHY format, pointing to the TBTT of the first PHY format. In some other implementations, the AP may enable the STAs to implement the changes at different times. For example, STAs using a first PHY format may implement the change at a TBTT of the first PHY format, whereas STAs using a second PHY format may implement the change at a TBTT of the second PHY format.

Abstract: A method, an apparatus, and a computer-readable medium for wireless communication are provided. In one aspect, an apparatus, e.g., an AP, may transmit, to a set of stations, a trigger frame comprising a request for feedback from each station of the set of stations and an indication of a plurality of resources for each station to provide the feedback. The AP may receive, based on the transmitted trigger frame, a feedback in one or more LTFs included in a response from at least one station of the set of stations. In an aspect, the feedback maybe a multibit feedback. The feedback from the at least one station may include at least one of a buffer status report, operating mode information, HE Link Adaptation information, uplink power headroom information, bandwidth query report information, or channel state information.

Abstract: Example methods, apparatuses, and computer-readable mediums for wireless communication are provided. In one example, an apparatus may be configured to determine a first interval between a first page transmission time and a second page transmission time. A third page transmission time may exist between the first page transmission time and the second page transmission time. The apparatus may be configured to enter a first state during which the first device is monitoring for a page transmission from a second device based on the first interval for a first state time period. The apparatus may be configured to enter, from the first state in response to a trigger event, a second state during which the first device is disabled from monitoring for a page transmission from the second device.
